Raspberry Pi 4 Model B 3GB Single-Board Computer

The Raspberry Pi 4 Model B 3GB is a compact single-board computer from Raspberry Pi, built around the Broadcom BCM2711 quad-core 64-bit processor. It offers desktop-class performance for its size, dual 4K display output, dual-band Wi-Fi, Bluetooth 5.0, Gigabit Ethernet and USB 3.0, while keeping the 40-pin GPIO header compatible with earlier boards. The 3GB version, introduced in 2026, sits between the 2GB and 4GB models for users who need more than 2GB without paying for 4GB.

Key Features

  • Processor: quad-core Cortex-A72 64-bit, considerably faster than Raspberry Pi 3 Model B+
  • Memory: 3GB LPDDR4-3200
  • Dual display: two micro HDMI ports with up to 4Kp60 output
  • Connectivity: dual-band Wi-Fi 802.11ac, Bluetooth 5.0, Gigabit Ethernet
  • USB: 2 × USB 3.0 and 2 × USB 2.0
  • Expansion: 40-pin GPIO, MIPI CSI camera and MIPI DSI display connectors
  • Power: USB-C 5V/3A, PoE with a separate PoE HAT

Where It Is Used

  • Learning programming with Python, Scratch and Linux
  • Home servers such as Pi-hole, Home Assistant or a small file server
  • IoT, sensors and automation through the GPIO header
  • Media centres and digital signage
  • School and university labs, robotics and maker projects

Which One to Choose

Raspberry Pi 4 Model B is available in several memory sizes. All versions share the same processor and ports; only the RAM differs.

Memory Best suited for
1GB Headless projects, IoT, light servers, learning Python
2GB Basic desktop use, Scratch, classroom coding labs
3GB (this product) In-between option: desktop use with more open applications
4GB Comfortable desktop use, browsing, web apps such as Tinkercad
8GB Demanding workloads, containers, multiple services at once

Package Contents

  • 1 × Raspberry Pi 4 Model B 3GB board

The board is supplied on its own. A USB-C power supply (5V/3A), a microSD card, a micro HDMI to HDMI cable and a case are sold separately.

Usage Tips

  • Use a quality 5V/3A USB-C power supply, such as the official 15.3W Raspberry Pi supply, to avoid undervoltage warnings.
  • Install the operating system with Raspberry Pi Imager on a Class 10 / A1 microSD card of at least 16GB.
  • Add a heatsink or fan for sustained heavy loads.
  • For 4K output use a micro HDMI to HDMI cable rated HDMI 2.0.

Frequently Asked Questions

What power supply does the Raspberry Pi 4 need?
A 5V DC USB-C supply rated at least 3A. The official 15.3W Raspberry Pi 4 power supply is the recommended option.

Is anything else included in the box?
No. Only the board is included. You will need a microSD card with an operating system, a USB-C power supply, a micro HDMI cable and ideally a case.

How many monitors can I connect?
Two, via the two micro HDMI ports. A single display runs at up to 4Kp60; with two 4K displays at the same time, 4Kp30 is recommended.

Is 3GB of RAM enough for desktop use?
Yes. 3GB is comfortable for everyday desktop use with a browser and office applications. For very heavy multitasking, choose 4GB or 8GB.

How does it differ from the Raspberry Pi 5?
Raspberry Pi 5 has a 2–3× faster CPU, a PCIe interface, a real-time clock and a power button, but it needs a 5V/5A supply and different cases. Raspberry Pi 4 remains a proven, lower-power choice with very wide accessory compatibility.

Does the Raspberry Pi 4 need cooling?
For light use it runs without extra cooling. Under sustained load, a heatsink or fan prevents thermal throttling and keeps performance steady.
